Discrete Cylindrical Vector Beam Generation from an Array of Optical Fibers [PDF]

open access: yesOptics Express, 2009
A novel method is presented for the beam shaping of far field intensity distributions of coherently combined fiber arrays. The fibers are arranged uniformly on the perimeter of a circle, and the linearly polarized beams of equal shape are superimposed ...

Three-dimensional acoustic vector field model using Gaussian beam tracing [PDF]

open access: yesJASA Express Letters, 2023
A three-dimensional acoustic vector field model was developed using Gaussian beam tracing. The field at any location is computed by coherently summing all contributing beams, where the beam equation of particle velocity depends only on beam width and ...

Generation of Vector Vortex Beams Based on the Optical Integration of Dynamic Phase and Geometric Phase

open access: yesPhotonics, 2023
The phase and polarization of electromagnetic waves can be conveniently manipulated by the dynamic phase and geometric phase elements. Here, we propose a compact optical integration of dynamic phase and geometric phase to generate arbitrary vector vortex

Toward a Corrected Knife-Edge-Based Reconstruction of Tightly Focused Higher Order Beams

open access: yesFrontiers in Physics, 2020
The knife-edge method is an established technique for profiling of even tightly focused light beams. However, the straightforward implementation of this method fails if the materials and geometry of the knife-edges are not chosen carefully or, in ...

Spin Hall Effect of Two-Index Paraxial Vector Propagation-Invariant Beams

open access: yesPhotonics, 2023
We investigate a simple paraxial vector beam, which is a coaxial superposition of two single-ringed Laguerre–Gaussian (LG) beams, linearly polarized along the horizontal axis, with topological charges (TC) n and −n, and of two LG beams, linearly ...
